Description

Breaking this out from KNOX-1559 where the changes were included. 

This allows for <param> to be set for dispatches both in service.xml and topology xml files. This sets the ground work for KNOX-1559 and others to use the parameters for customization of behavior. It avoids the need to hardcode additional parameters when customizing dispatches.

An example from KNOX-1559 could be something like this:

<dispatch classname="org.apache.knox.gateway.dispatch....">
  <param>
    <name>excludeRequestHeaders</name>
    <value>Authorization,Content-Length</value>
  </param>
  <param>
    <name>excludeResponseHeaders</name>
    <value>SET-COOKIE,WWW-AUTHENTICATE</value>
  </param>
  <param>
    <name>removeUrlEncoding</name>
    <value>true</value>
  </param>
</dispatch>
